[patch]: qemu-xen: pass-through: pt_reset_interrupt_and_io_mapping(): use hw INTX
This fixes a few things that I missed in previous patches:

This is consistent with other uses of pci_intx()
* Remove now inaccurate "/* fix virtual interrupt pin to INTA# */" comments
* Use PCI_SLOT()

[PATCH]vtd: Fix for irq bind failure after PCI attaching 32 times
vtd: Fix for irq bind failure after PCI attaching 32 times
Originally when detaching a PCI device, pirq_to_emuirq and pirq_to_irq are freed via hypercall do_physdev_op. Now in function pt_irq_destroy_bind_vtd, duplicated logic is added to free pirq_to_emuirq, but not pirq_to_irq. This causes do_physdev_op fail to free both emuirq and irq. After attaching a PCI device for 32 times, irq resources
